Gas Up and Cool Down

Purge existing cargo tank content (e.g. Nitrogen Gas, other product vapor) until Nitrogen requirement by the next cargo e.g. LPG 2%, VCM 1%.

Once the product vapor reaches 99% or better, stop the purging (venting off the Nitrogen plus product vapor) and pressurize to say, 1 barg.

Use liquid of the product to “cool” the cargo tank by flowing through the spray bar inside the cargo tank. Once the temperature of the cargo tank is cooled down to the desired level, operation is stopped.

We provides Nitrogen gas-free services, gassing up and cool down services for refrigerated Propane, refrigerated Ethylene and Propylene.
